THOMAS F. I-IAGERTY, OF NEW YORK, N. Y.; GEORGIANA. I. HAGERTY ADMINIS-TRATRIX 0F SAID THOMAS E. HAGERTY, DECEASED.

SELF-LOADING SCRAPER.

Application filed February 13, 1915.

To all whom it may concern:

Be it known that I, THOMAS F. HAGERTY, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented new and useful Improvements in Self Loading Scrapers, ofwhich the following is a specification.

This invention relates to self-loading scrapers to be used for streetcleaning purposes, and it has particular reference to that class ofscrapers which are wheel supported and are operated like a push cart toaccumulate a load by scraping up loose material in front and carrying itinto the body of a box-shaped scoop which, when loaded, may be tilted todischarge the contents into a receptacle.

One object of the invention is to produce a skeleton frame of simple andimproved construction, said frame including side members which arespaced apart and provided with wheel carrying spindles, the scoop orscraper being pivotally connected with such frame.

A further object of the invention is to so construct the frame that itwill support the free end of the scoop above the ground, said framebeing provided with a scraper blade to engage the surface of the ground,thus obviating the wear on the edge of the scoop.

A further object of the invention is to simplify and improve theconstruction of the scoop, the sides and bottom being formed of oneintegral sheet of steel.

A further object of the invention is to provide the frame with pivotedlegs or crutches whereby it may be supported while the scoop is beingtilted to unload the same.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaims may be resorted to when desired.

vation of a scraper cart constructed in accordance with the invention,dotted lines being employed to show the position of the scoop whentilted to unload the same. Fig. 2 is a top plan view with parts brokenaway. Fig. 3 is a perspective detail view of the pivoted leg or crutchand related parts. Fig. t is a side elevation of the device seen fromthe opposite side to that shown in Fig. 1. 5 is a longitudinal sectionalview taken. on the line 55 in Fig. 2. Fig. 6 is a horizontal sectionalview taken on the line 66 in Fig. 1.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The frame F of the improved device is substantially rectangular,comprising the side members 15, bottom cross bar 16 and top cross bar17. The frame may be conveniently formed by bending from a single pieceof channel iron or other appropriate material. The side members 15 areprovided with spindles 18 carrying the ground wheels 19, said spindlesbeing positioned intermediate the ends of the side members. The crossbar 17 constitutes a handle whereby the device may be convenientlypropelled.

The side members of the frame are connected intermediate the spindles 18and the cross bar or handle 17 by a cross bar 21 on which the box-likereceptacle or scoop R is pivotally supported. The side members of thereceptacle are connected together at their upper end portions by a frontapron 22 having a handle 23 whereby the scoop may be manipulated intilting. The bottom portion of the scoop is inclined downwardly andforwardly, and the forward or lip portion thereof rests on a scraperblade 24 detachably connected with the top of the cross bar 16 of theframe. The scoop has an upwardly extending neck 25 which is preferablyprovided at its upper edge with a bead or flange 26 below which aclamping ring or band 27' is arranged for the purpose of retaining inposition an inverted bag or a similar receptacle.

Pivotally mounted on the cross bar 21 adjacent to the outer faces of theframe members 15 are legs or crutches 28, each having at its upper end alaterally extending arm 29. These legs are normally moved in a forwarddirection so as to hold the lower ends thereof clear of contact with theground by the action of springs 30 which may be ordinary coiledcontractile springs, each having one end connected with the frame andthe other end with one of the legs 28. The legs may be swung to a groundengaging position, as seen in dotted lines in Fig. 1, and the frame willthus be supported in a non-tiltable condition while the receptacle isbeing tilted for the purpose of discharging the contents. The laterallyextending arm 29 constitutes a stop member which, by engagement with theside member of the frame, will limit the swinging movement of the le ina rearward direction.

Pivotally connected with the scoop or receptacle adjacent to the loweredge of the apron 22 is a gate 31 having adjacent to its upper edge anupwardly extending arm or crank 32 which is pivotally connected to theforward end of an operating bar 33, the rearward end of which is guidedthrough a keeper 34: on the rearward end of one side of the scoop, therearward end of said operating rod terminating in a handle 35 whereby itmay be manipulated to move the gate to an open or to an obstructingposition with regard to the rearward portion of the scoop. The rod 33may be provided with notches 36 adapted to engage the keeper for thepurpose of looking or retaining the gate in an open or in a closedposition, as may be desired.

From the foregoing description, the ope1 ation and advantages of thisinvention will be readily understood. The frame, it will be seen, is ofextremely simple construction, and it will support the scoop orreceptacle practically clear of the ground, the scraper blade 24attached to the cross bar being in a position where its ground engagingedge will effectively scrape the surface of the ground. Shouldobstructions, such as frozen matter,

be encountered, the operator, by lifting up the handle 17, may readilypick up the same, the frame and scraper being rigidly connected. Bypushing the device over the surface of the street, rubbish and litter ofall kinds may be conveniently gathered in the receptacle, it beingobvious that by occasionally bearing down on the handle so as to liftthe forward end of the scoop, the accumulating material may be thrownback into the rearward part of the scoop, the gate 31 having beenpreviously moved to an open posi tion. When the material has been thrownback into the rearward portion of the scoop, the gate 31 is restored toits obstructing position, as will be readily understood. When it isdesired to discharge the contents of the scoop the legs or crutches 28are moved to ground engaging position, as seen in dotted lines in Fig.1, holding the frame stationary, and the scoop may then be tilted, asshown, thereby discharging its contents either into a can or otherreceptacle previously placed in posrtlon or into an inverted bag whichhas been previously connected with the neck of the scoop by the bagholding element 27. The device is capable of being operated in athoroughlv effective manner and with less exertion and strain on thepart of the operator than is usually required to accomplish similarresults.
